SUPERHEAT-BEGULATOR non s'rsm-osnsaa'ro'as.

To all 'whom it may concern:

Be it known that I, Jam H.'Roseu'rnan, a subject of the Kin of Great Britain, residing at Kemnal Ianor, Kemnal Road, Chiselhur'st, Kent, E land, have invented certain new and 'usefil Improvements in superheat-Ret'gulators for Steam-Generators,

ollowingis a specifieation.

The present invention is an improvement upon that of my PatentNo. 1;096,128, dated May 12, 1914, and relates tomeans for eflecting the regulation of the superheat of steam by diverting the superheated steam wholly or in part from its-palssa e to the stop valve or main and leading e diverted steam through .an attemperator fitted in the steam generator drum. With the, arrangement described in the said prior patents the mini mum limit of temperature to which the superheated steam could .brou ht was necessarily above that of satura steam, as the temperature of the water or steam iminediately surrounding theqattemperator is not sutiiciently low to provide the r uisite thermaL head -for the transference 0 heat into saturated steam.

According to the present. improvement-or modification,- in order-t0 extend the range of reduction of the temperature of the superheated steam, so that the'latter may, if de-' sired, be rcconverted into saturated steam, and to permit of reductionlof the dimensions of the attempera-tor, etc., tlfe attemperator is located in that part of the drum receiving and containing the feed water. f

The inven-ion will be understood by reference to the accompanying drawings in which I i Figure 1 is a side elevation of a steam and water drum showing the invention applied thereto; F ig. 2 a transverse section on the planes of the line 2-2; and Fig. 3 a

required toconvert the superheatedsteam sectional detail of one of the valves.

stop valve e and the other branch leading to the mixing valve (1 by way of theattem perator g fitted within the boiler drum )1. The attemperator g is represented as being Specification 0! Letters Patent.

ftemperator' gvis. so positionedih relation to the feed Water inlets 7' that inflowingfeedwater will impinge thereon andis ihclosed within a compartment formed-by the wall" of the drum and diaphragms or partitions 1;, whereby the feed-water is cutoff froni the main body of feed-Waterand the tempera-- ture within the compartment may. be maintained considerablyllower than that in the rest of the interior of the drum. At the junction of the branches 0 and f is fitted the mixin valve-d, shownin section in Fig;

3, adapte to control the communication be i tween the branches 0 and stop-valve e.

f and the main It will be understood that in the opera-' 11a tion' of the invention superheated Steam is; led by the connection/1 and according to'the.

position of the mixing .valve the ratioof the volume of steam flowing ,throughthe branch 0 to that flowing through therb'ranchf, f, including the attemperatorcafri .be ad? '.jus te'd and thereby the. degree of su'perheat regulated. In one extreme position of the mixin valve the entire volume or the super'-.

heat steam may be cause 1 to flow through the branch 0 and thus to by-pass the'attem-{ perator; while in the other extreme position of the mixing valve the entir e volume of.

steam from the superheaterf through the attemperator. I

As shown in Fig. 2 the compartment formed by the partitions Lis opened at the lower part thereof tor-permit the escape of f the feed water from the compartment into the drum.

'2. The combination with a steam boiler (ll-um. of a superheated steam attemperatorr therein, a partition forming a compartment mar in which said "it?!" "ator is posibioncd, and a feed water ink N said coflipartmut.
